Consensus among stakeholders about success factors and indicators for quality of online and blended learning in adult education: a Delphi study

Quality models for online and blended learning (OBL) have mainly been developed in higher education. The literature indicates that these models are often conceptualised from the providers’ perspective. What is important for the quality of OBL from the students’ perspective has recently received increased attention in the literature. Consensus among stakeholders about students’ quality needs is useful to support dialogue between professionals to strategically adopt OBL and to ensure that the needs of students are met. This study aims to validate a quality instrument for OBL, taking a set of 74 quality indicators and analysing them in terms of seven success factors (credibility, accessibility, transparency, flexibility, interactivity, personalisation, productivity). The Delphi method was selected as most suited. Participants from adult education were asked to indicate on a 7-point Likert scale to what extent the indicators add to OBL quality to meet students’ needs. After four Delphi rounds, the participants agreed on definitions of success factors and 30 indicators. The results are useful for institutions, ministries of education and external quality assessment agencies to assess the quality of OBL and can support institutions to implement improvement actions to ensure that the needs of students are met.  相似文献   

Assessment,Grade Level and Learning     

Agnes Chang Shook Cheong 《Asia Pacific Journal of Education》1992,12(2):35-47

Researchers have identified assessment as a very crucial influence on the learning strategies adopted by students. The present study carried out on Secondary 2, Secondary 4, and Junior College 2/Pre-University 3 students shows that the Singapore students did not favour the Surface Approach in their learning of English and Mathematics. The nature of the discipline and the cognitive demands of the examinations carried considerable importance for students in their choice of learning strategies. Despite the heavy emphasis on excelling in examinations, students did not rely solely on surface and achieving strategies to attain their goals.  相似文献

杨丽红  丁长海 《泉州师范学院学报》2003,21(2):115-118

为适应城市居民生活“小区”化和以建设“明小区”为重点的社会工作路线，改变目前社区体育组织以“街道”为单一层次的基本结构，本课题采用献法、调查法、比较及逻辑法等，对“小型化”社区体育组织的现状、目标及发展模式进行了深入研究，并提出了辐射型、网络型、独立型三种递进式组织结构模式，为社区体育组织结构的转型发展提供参考依据。  相似文献   

The rewarding effects of number and surface area of food in rats     

Devina Wadhera  Lynn M. Wilkie  Elizabeth D. Capaldi-Phillips 《Learning & behavior》2018,46(3):242-255

Visual cues have an important role in food preference for both rats and humans. Here, we aim to isolate the effects of numerosity, density, and surface area on food preference and running speed in rats, by using a forced-choice maze paradigm. In Experiment 1, rats preferred and ran faster for a group of multiple smaller pellets rather than a single large pellet, corroborating previous research (Capaldi, Miller, & Alptekin Journal of Experimental Psychology: Animal Behavior Processes, 15(1), 75–80, 1989). Further experiments tested the prevailing hypothesis that multiple food pieces are more reinforcing because they occupy a larger surface area. Experiment 2 controlled for numerosity by utilizing a continuous food: mashed potatoes flattened to cover a larger surface area or rounded into a ball. The rats preferred and ran faster for the flattened potatoes, suggesting surface area plays a role in quantity estimations. Finally, in Experiment 3, rats displayed no preference or difference in running speed between a group of scattered and clustered pellets when number of pellets were kept constant. Taken together, these results suggest that density has an important role in food perception—that is, the rewarding effect of higher numerosity or larger surface area is removed when the food does not fill out the entire space. Alternative explanations and implications for human diet are discussed.  相似文献   

论党在早期工人运动中解决帮会问题的策略     

房晓军  胡长青 《淮阴师范学院学报(哲学社会科学版)》2001,23(1):83-86

中国共产党成立以后就着手开展工人运动 ,首先遇到的障碍是帮会。由于在工厂、码头、矿山、货栈等有劳苦工人的地方 ,几乎都有帮会的活动 ,又由于帮会在思想上禁锢着工人群众的觉悟 ,在组织上限制着工人群众的自由 ,阻碍工人运动的发展。为此 ,我党制定了一系列妥善处理帮会的策略 ,排除了帮会对工人运动的干扰 ,有力地推动了中国革命。  相似文献
